Wilt (1989)

"Wilt" is a consistently amusing film throughout which perfectly uses the comedy of extreme embarrassment to good effect as Henry Wilt bungles his way from one improbable - yet never entirely implausible - catastrophe to the next. The many twists and turns it takes are completely unanticipated until the very end when it becomes perfectly clear Wilt's wife Eva is very much alive and she has inadvertently stumbled into the clutches of the strangler and, even though this character has been referenced elsewhere earlier on in the film, this doesn't spoil the fun in any way. The finale has lots of comedic energy running through it to sustain it until the very end and the film as a whole is satisfactorily concluded on every level.
